New Distribution Capability (NDC) in air travel: Airlines, GDS and the impact on the industry

This article is a redacted version of a post that originally appeared on the Altexsoft blog. It is republished here with permission.

Two fundamental needs connect all airlines: revenue and passenger satisfaction. To satisfy customers, carriers seek ways to learn more about their clients and provide a set of additional services like baggage insurance or onboard food. Those services, also called ancillaries, are offered for additional fees. Given the small margins for core transportation services, the fees help to generate profits.

To be able to sell ancillaries to the passengers and be more profitable, airlines struggle to deliver personalised content to their travelers. Considering that getting in touch with the end user is nearly impossible via the channels provided by global distribution systems (or GDSs), a new standard emerged to resolve the issue.

The air travel industry confronted big changes when the New Distribution Capability (or NDC) debuted in 2012. Lufthansa, British Airways, American Airlines, and Iberia were the first to adopt NDC. And the technology continues to make its way in airline distribution, as well as other means of improving airline operations.

What is NDC?

NDC stands for the New Distribution Capability, which is essentially an XML standard created by the International Air Transportation Association (IATA) to allow airline service providers to deliver rich content and ancillaries to their customers. Basically, NDC is a communication protocol, aimed at replacing the old EDIFACT protocol, that has been around since the 1980s and used by GDSs.

A new protocol using XML allows for bringing rich content and ancillaries directly to online travel agencies, GDSs, and travel management companies via a set of standard APIs, used in the travel industry. Additionally, XML is much more flexible and updatable.

What benefits does NDC provide?

Personalised shopping experience and access to customer information. Currently, most of the customer personal data remain in the hands of middlemen, OTAs and GDSs. This means that airlines get just basic information about their clients, which doesn’t allow for personalising the shopping experience, the thing that has become a standard in modern travel eCommerce. The NDC standard’s goal is to provide airlines with direct information about their customers.

Content and pricing autonomy. Another benefit of personalisation is pricing autonomy. Currently, most airlines publish their tariffs via ATPCO, the tech provider and main source of pricing data. Having a third party as an intermediary between revenue management and distribution channels means that airlines miss the opportunity of dynamic pricing. Dynamic pricing is the ability to create personalised fare and travel package offers based on individual client information. The new XML standard allows airlines to build their own APIs and change prices independently adding value to their offers and adjusting prices individually to each customer.

Rich content offers, ancillaries, and discounts. Distributing the flight data via GDS’s EDIFACT (Electronic Data Interchange for Administration, Commerce, and Transport), airlines are unable to include ancillaries in their offers. This results in financial losses for service suppliers as ancillaries are the main source of profits for carriers.

Product differentiation. The traditional GDS model only permits airlines to display prices and schedules. While tariff metasearch engines and OTAs make it easy for travelers to compare pricing, airlines can’t market their added value services and fully compete. Rich content, that includes all service details, solves this problem.

Reduced reliance on legacy systems. Most airlines use legacy passenger service systems (PSS) that contain reservation info, fares, and schedule. The main purpose of the PSS is to show which seats are available for a given flight. PSSs may have poor performance, a number of other restrictions, and most PSS providers really lag in modernisation. NDC will act as a separate engine outside of legacy systems that allow for presenting data stored in PSS databases using airlines’ private interfaces.

The first set of official standards was released on September 1, 2015. A new messaging standard promised to change the way airline tickets are distributed. This will help service suppliers bring personalised content directly to OTAs, TMCs, and metasearch engines, bypassing Global Distribution Systems (GDSs). As a result, NDC was supposed to break the oligopoly of GDSs that formed over time.

To understand the current situation in airline distribution and get a detailed background on why NDC has emerged, we need to look back in time.

How airline distribution works: historical and modern perspectives

The distribution system in the air travel industry includes many players in the field. To link end customers with the actual airline, there are a number of intermediaries, represented by travel agencies, tariff publishers, GDSs, and so on. Most of the major players appeared decades ago or morphed from the older formations and continue to exist.

Let’s have a deeper look at the airline distribution landscape from the historical perspective. This will allow for a comprehensive understanding of the current state of NDC adoption and the roles of the players involved.

The timeline of flight distribution in the air travel industryFlight distribution automation. In 1964, IBM and American Airlines developed the first computer reservation system Sabre, which is still around today. Sabre allowed American Airlines ticketing agents to search for flights using digital inventory, make reservations, and confirm them via computer terminals. It also decreased the error rate and gave access to customers’ PNR (Passenger Name Records). Sabre quickly became a serious advantage for American, resulting in the appearance of more Computer Reservation Systems (CRSs).

Central reservation systems emergence. Until 1972, nearly all major airlines in America adopted their own customised versions of CRSs. All of them originated from PARS – a standardised system for medium-size carriers by IBM.

Bringing terminals to travel agents. During the 1970s, all CRS providers struggled to bring their systems to travel agents, installing terminals at their offices to make searching for flights and booking semi-automatic and remove the booking load from airlines. The American Society of Travel Agents and airline platform providers attempted to create a unified CRS for all travel agents. As a result, in 1976 United, American, and Eastern airlines shared access to their CRSs. Airlines offered to travel agencies long-term contracts, for which they supplied hardware, software, and training for a monthly subscription fee to get most of the bookings made via CRS. In exchange, travel agents were obliged to book more via CRSs.

Price independence. The Airline Deregulation Act of 1978 allowed airlines in the USA to set the price for fares independent of government regulations. This influenced the market and the demand for CRSs among travel agencies increased even more.

Mass CRS adoption. By 1989, over 95 percent of travel agents signed contracts with CRS providers, and 75 percent of all tickets were booked via travel agencies.

GDSs join the game

GDS emergence. After 1996, the US Transportation Department obliged airlines to share the same content from their inventories across all CRSs equally. Meanwhile, CRSs started to become independent businesses. For instance, Galileo CRS, created by European airlines to compete with Sabre, went public in 1997. Amadeus, another European CRS, did the same in 1999. Sabre became fully independent of American in 2000. That moment can be considered as the point of Global Distribution System (GDS) emergence in the world as CRS providers grew into GDSs and became an independent, fast growing power, morphing from inventory instruments to monopolists in air travel distribution we know today.

GDS consolidates travel data from various service suppliers and allows travel agents to search and book flights. So, for the travel agencies and for customers as well, it’s not necessary to connect directly to each supplier. Currently, the major GDSs are represented by Sabre (including Abacus), Amadeus, and Travelport (Apollo, Galileo, and Worldspan). This doesn’t mean that CRSs have disappeared. They became the parts of passenger service systems, or PSS, which also include airline inventory and departure control systems.

Meanwhile, GDSs settled Internet connection, providing travel agencies with the software to build their own websites. So, new channels of distribution came up via the web, and online travel agencies (OTAs) emerged.

Third-party players in airline distribution

The distribution system also includes third parties that perform either supplier or intermediary roles between airlines and other players:

OAG, a United Kingdom-based provider of digital data and applications for the flight industry, manages the largest flight schedule database for over 4 thousand airports.

Innovata is another schedule database provider, being a strategic partner of IATA.

In a GDS-centered distribution, these tech providers play an important information role, preventing airlines from fully owning their data. For instance, to change prices, airlines must publish them via ATPCO first.

Recent events and NDC background

A new issue appeared during the late 2000s. GDSs failed to support airlines in sharing their rich content across OTAs, giving no options to merchandise additional services, thus cutting down revenue. According to the IdeaWorks’ ancillary revenue report of 2009, worldwide ancillary revenue reached €11 ($13.5) billion. Without any doubt, offering bundled services to the right customers became a critical task for service suppliers. But, the GDS oligopoly with its old-world EDIFACT protocol technically doesn’t allow for distributing rich content and acquiring customer personal data.

Generally, two main events impacted NDC emergence and its further adoption among airlines.

American Airlines vs Sabre lawsuit. The lawsuit was initiated by American Airlines and US Airways to persuade a jury that Sabre was in violation of the US antitrust law. The carriers sought compensation for financial losses associated with the Full Content Agreement that GDSs force airlines to sign. According to the agreement, carriers had to publish all their inventory via GDSs. The lawsuit, which lasted over 6 years, resulted in Sabre having to pay $5 million in compensation. The case attracted the attention of industry representatives. The jury found the Full Content Agreement unlawful, but the compensation didn’t even cover 1 percent of American Airline’s losses.

Lufthansa GDS surcharge and direct bookings. The German flagship airline, Lufthansa, in the summer of 2015 announced that it would surcharge every booking made via GDS €16 ($18). The initiative was called a Distribution Cost Charge, and it put a lot of pressure on travel agencies, as it was a step away from the traditional GDS distribution model. Nevertheless, Lufthansa took further action, paying travel agencies one euro for every flight booked via their NDC channel. British Airways and Iberia began penalising bookings via GDS. The charge was £8/€9.50 (about $11) respectively.

In 2017, Lufthansa moved away from GDS and established direct channel bookings on their website. The Lufthansa Group began offering discounts for booking via their NDC channel. This move led travel agencies to invest in direct connection technical infrastructure needed to create a GDS-free middle ground. As an IT provider, Farelogix got a contract with Lufthansa to expand its NDC API, and support its adoption among travel agencies using it.

The current state of NDC adoption

Currently, representatives from nearly all parties in airline distribution have embarked on the NDC initiative one way or another.

According to the latest IATA NDC program update, the list of certified deployments reached 65 carriers. The number seems to have grown significantly since 2017 when IATA reported only 50 airlines adopting NDC. But, compared to the overall number of airlines connected to the major three GDSs, which is over 400, NDC adopters seem to be a minority.

The report also includes information about the 46 IT providers offering NDC solutions development and implementation.

In 2018 IATA published a presentation of NDC standards, that includes new data on the number of airlines adopting NDC and IT providers.

NDC adopters among airlines

Major airlines managed to develop their NDC solutions, which sometimes differ in implementation. Here are some examples of NDC implementation across airlines.

Lufthansa was the first one to introduce a GDS surcharge and implement direct booking connection in its distribution. Currently, Lufthansa’s direct booking includes several distribution channels: travel agencies direct, aggregators, supplier mobile application, and supplier website. While its NDC version allows for offering rich content, the support of personalised bookings is still to be reached.

British Airways developed an NDC solution and integrated it with Kayak. Now their tickets are available directly through the Kayak platform. British Airways API allows for distributing through the following channels: direct connect through OTAs, IATA’s travel agents, GDSs, and online booking tools. Similar to Lufthansa’s API, British Airways doesn’t support personalised bookings yet.

Air Canada allows their API to be used freely across all channels. It seems that Air Canada presents the fullest range of NDC “advantages” for the moment, providing rich content, personalised bookings, airline profiles, air, and non-air related ancillaries.

Flydubai also has a competitive NDC implementation, being relatively equal to what Air Canada offers. The only difference is that Flydubai allows for distribution only through travel agencies and OTAs.

So, only a few among the NDC adopters have managed to present the full range of NDC benefits. Others are still establishing the connectivity between the distributors to get their direct channels to work.

IT providers of NDC solutions

IT providers are the companies offering tech services for the industry, including API development and their implementation at airlines. The list of IT providers, that are certified by IATA and showcase a large number of implementations, includes:

SITA, a global tech (IT) and communications provider in the airline industry. As SITA has a partnership agreement with ATPCO, they developed an NDC Exchange platform. NDC Exchange is an industry-owned platform that will help to deliver air price content via NDC APIs.

Farelogix is a technology company that provides SaaS (Software-as-a-Service) NDC solutions for American Airlines, Air Canada, and Delta. In 2017 it was announced that Farelogix will be acquired by Sabre, the deal to be sealed in early 2019.

OpenJaw Tech is an IATA certified strategic partner that also provides NDC solutions for the market. OpenJaw Technologies is known for supporting such airlines as British Airways and Iberia. IATA has also chosen OpenJaw Tech to be their One Order strategic partner.

Travelsky is a Chinese general IT provider of SaaS solutions to NDC adopters.

All the IT providers should be certified by IATA to develop their tech solutions for the airlines and other third parties. The certification NDC program can be found on IATA’s website.

Disadvantages and difficulties with NDC

Despite being a great opportunity, NDC has at least two major drawbacks that slow down its adoption across all major carriers.

NDC is not really a standard. The use of XML instead of EDIFACT is supposed to be a standard, but in reality, the implementations are different and depend on the IT provider. So, there is no real “standard” for all. That means that if every airline would plug into their own NDC pipeline, there would be countless API channels impossible for OTAs and TMCs to integrate with. The only winners in this situation seem to be IT providers.

Distributors won’t leave the GDS pipeline. Travel agents are still more likely to use GDSs because they don’t require any changes and still generate revenues. For OTAs and TMCs a switch to NDC means additional expenses which don’t guarantee any benefits. The reason for that is a severe market fragmentation with different NDC solutions and no one-size-fits-all solution. For instance, American Airlines reported 4 million tickets sold via its NDC channel in 2017, which doesn’t look like a large percentage of annual revenue. Today, NDC adoption remains a premium option, rather than a necessity.

Considering the fact that distributors are more likely to stick with GDS, you may ask a reasonable question. Why wouldn’t GDSs adopt NDC?

NDC adoption across GDSs

The latest announcements made by the major GDS companies point out that they won’t quit the game yet. Obviously, GDS remained an all-purpose option for OTAs and TMCs. All three GDS giants have announced that they are going to participate in NDC adoption as a part of airline distribution evolution.

Travelport was the first of GDSs to obtain level 3 compliance as an NDC aggregator, which is a required status to provide NDC services. Travelport’s NDC product was presented in 2017 via a roadmap, and it was announced that the product will be initially designed for airline companies. But the product will be enhanced in 2019 to be integrated with OTAs.

SABRE made an official announcement at The Beat Live in October 2018, that it will reach level 3 compliance as an aggregator of NDC. That said, Sabre was recognised by IATA as a level 3 NDC IT provider in early 2018. The compliance level recognition means that the company is compatible with IATA’s NDC standards and is able to provide a full range of services.

Amadeus is developing its NDC-X program, and has also reached level 3 as an NDC aggregator.

For GDS aggregators, NDC adoption became a vital question. As it’s impossible for GDSs to integrate with each separate NDC channel, they decided to force the adoption of an XML standard for the industry. The process goes even further as all parties of a traditional distribution chain start adopting NDC. In October 2018, ATPCO announced its collaboration with SITA, an IT provider, to develop a simple API for NDC adoption.

NDC will come, but via GDS

The New Distribution Capability was supposed to allow airlines to bypass GDS. The current state of the industry vividly illustrates that as of 2019, GDSs are likely to remain the oligopoly even in terms of NDC adoption. As airlines will still be able to merchandise their additional services through NDC pipelines, they seemingly have achieved their goals. But the question is more about the transparency now, as it is a big question whether GDS NDC aggregators will allow carriers to directly reach their customers.

The only party left in uncertainty are distributors represented by various travel agencies that will have to wait until each airline/GDS is ready to switch to its NDC solution.
